    I have a 2007 Volvo 670 with 930000 miles on the Cummins ISX cm870. at idle it's stuttering almost like it's gonna cut off. it doesn't do it but half the time and it goes away after a few seconds. a mechanic told me it was the fuel actuators going bad he can't tell me which one and I have to change them all does that sound correct? Is there no way to test them I had the computer put on the truck and it's not showing any active issues.

    I would never use that shop again. You can test them acturators It could also be a injector problem. Just because a cut out test pass don't mean it's not bad. If you got Facebook. Look for a group Cummins isx problem solvers
    Rawze is also a good site!
